Quad Power
The Quad XP-581 from Elenco provides four separate, fully regulated power supplies. Three are fixed and yield +5 VDC at 3 amps, -12 VDC at 1 amp, or +12 VDC at 1 amp. The fourth supply is variable, producing 2.5 to 20 volts of DC output at up to 2 amps. Line and output voltages are regulated to within 0.05 volts, and the supply is linear. All four supplies are shortproof as well. A current foldback circuit in each supply collapses the field in the event of a short, a current surge from the line, or an excessive current demand. Thus, both the Quad XP-580 and the equipment it's driving are normally protected from inadvertent errors or power company problems. Elenco built the supply as only Elenco will. The handsome, hooded metal case, - measuring 3-1/4" x 8-1/4" x 9-1/4" and weighing nine pounds - has a 3-wire grounded power cord for 115 VAC operation, panel meters for both current and voltage, and standard jacks for accessing the four regulated supplies. A two-year limited warranty and schematic is also included.

Sashette Chain
Shiny brass chain of the sash persuasion. Light duty and only 1 ft long, Purchasing says it is for industrial doll houses. Over here in Editorial, we believe less and less of what Purchasing tells us. So we suggest you use it to secure the chuck key to a tool, a roll of electric tape to your belt, or someone from Purchasing to his cubicle. (They are all quite puny.)

Lazy Scott Bearings
Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square, flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" version is rated for a 300lb. load, the 6" for 500lbs., and the 12" (round) for 1000lbs.
